Answer:
47,759
Step-by-step explanation:
77 + 216 x 326 then divide by 2
Answer:
Javier has 27, Tommy has 16
Step-by-step explanation:
43-11=32
32/2=16
16+11=27
Check: 27+16=43
The roots of the equation are 2 and k
substituting x=2 in the equation
(x+4)(x-p) = 2-x
(2+4)(2-p) = 2-2
6(2-p) = 0
dividing 6 both side, the answer is
p = 2
substituting x in the equation we
(x-4)(x-p) = 2-x
x² - 2x + 4x- 8 = 2-x
x² - 2x + 4x -8 -2 -x = 0
x² + 3x - 10 = 0
x² + 5x -2x - 10 = 0
x(x + 5) -2( x + 5) = 0
(x + 5)( x - 2) =0
(x + 5) = 0 or (x - 2) = 0
x = -5 and x = 2
therefor k = -5 and p = 2
The two packages mailed together is cheaper.
If seperately:
3 pounds package= $(x+2y)
5 pounds package= $(x+4y)
If combined:
3+5=8 pounds
= $(x+7y)
amount of money saved=$[(x+2y)+(x+4y)]-$(x+7y)
5 = p/4
To solve for P, multiply both sides by 4:
p = 5 x 4
p=20
